The effect of two environment water - moss and peat moss soil on the number of cocoons, the weight of the cocoon and the number of casualties of oriental leech (Hirudo orientalis).

In recent years, leeches have been used to treat some diseases, extract many enzymes and substances that are effective in treating diseases.This study aims to influence the two environments of water-moss and peat moss soil on the number of cocoons, the weight of the cocoons and the losses in the oriental leech.

For this purpose, 300 productive leeches for 45 days in 6 treatments and 3 repetitions per treatment: treatment (1) 10 leeches in water-moss, treatment (2) 15 leeches, treatment (3) 25 pieces Leeches, treatment (4) 10 pieces of leeches in Peat mosss, treatment (5) 15 pieces of leeches, treatment (6) 25 pieces of leeches. Reproductive leeches were kept in a water-moss environment in tanks containing 50 liters of chlorine-free water at 28-27°c. The mosses were controlled and sprayed twice a week, and the cocoons inside the mosses were collected and stored at 25°c. Productive leeches were kept in a 10-liter plastic container in the soil of Peat mosss. The peat moss soil was inspected 3 times a week and sprayed to retain moisture, and cocoons were collected inside the moss soil and stored at 25 °c in the peat moss soil.

The results showed that the number of cocoons produced in water-moss and paet moss soil did not differ significantly (p <0.05). The weight of the cocoons produced in the two environments did not differ significantly (p <0.05). Also, the number of casualties of productive leeches in the two environments showed no significant cifference (p <0.05).
